BALlNG-PRESS.

FJPECIPICATION forming part of Letters Patent No.367q932, dated August 9, 1.887. Application filed January 3, 1887. Serial No, 223,235). (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM W. SEELEY, of the city and countyof Albany, in the State of New York, have invented new and useful Improvements in Bailing-Presses, of which the following is a specification.

My invention relates to improvements in baling-prcsses that are operated by animalpower, the same being an improvement on Patent No. 332,291, granted to me December 15, 1885; and the object of my invention is to provide a novel device for automatically increasing the leverage of the pressing mechanism to correspond to the requirements of the operation of pressing. I attain this object by the mechanism illustrated in the accompanying drawings, which are herein referred to and form part of this specification, and in which Figure l is a plan View of the power end of my press, that being the only part that is affected by my invention; Fig. 2, a longitudinal section of same with the pressing mechanism shown in elevation, and Fig. 3 a horizontal section with the pressing mechanism at a different point of its movement, shown view. s

As represented in the drawings, A is the framework of the press, of which only the part affected by my invention is shown.

B is a stationary shaft held by the crossbars a of the frame-work and forming a pivotal center for the working-beams G and sweep D. The double arms or workingbeams C, of which there are preferably two, one directly above and the other directly below the sweep D, are each provided with a longitudinal slot, 0, through which the shaft .B passes, and by reason of said slots the working-beams O can receive automatically an endwise-sliding movement, whereby the leverage of the workingbeams will be increased as the plunger of the press is forced inwardly, the leverage of said beams being least when in the position shown in Fig. 3 and the greatest when in the position shown in Fig. 1; and it will be readily seen that thisvariation of leverage is in correspondenee to the requirements of the work that is to say, a quicker movement of the plunger, and consequently exerting less power, is produced when there is the least resistance to the plunger and a slower movement and a corin plan responding increase of power when the plunger is meeting the greatest resistance.

The sweep D is preferably made of. two beams, whose butts are fastened to a crossyoke, d, and their opposite ends secured to each other, so that they, in connection with the cross-yoke d, are arranged to form an isosceles triangle. The cross-yoke d is provided with a central opening, through which the shaft B is fitted, so as to permit the sweep D to vibrate freely thereon. V

The working-beams O are pivotally con nected at one end to the pitman E and at the opposite end to links F. The pitman E is pivoted, as at e, to a plunger, G, which is fitted to slide freely inwardly and outwardly in the pressingchamber a. The links F have longitudinal slotsf; which engage with studs d formed on the bridge-piecesd, that are secured to the two arms of the sweep D. The studs (1 are adapted to engage in the outer ends of the slotsf, and the latter should be extended to a sufficient distance toward the working-beams O to permit the latter to swing around on the shaft B when the rebounding movement of the plunger G occurs, as hereinafter described.

The friction-rollers H are arranged at opposite sides of the press, where they will lie in the path of the pitman'E while the plunger is making an inward stroke, so as to aid the working-beams O in making their sliding movements. may be substituted for the friction-rollers H, and when such blocks are arranged in place like said rollers they will produce a like effect.

It will be seen that theworking-beams O and pitman E form the two parts of a togglejoint similar to those in common use, the material point of difference in them being the shifting of the short arm of the togglejoint in respect to its fulcrum in my device.

The operation of my press is as follows:

' The parts being in the position shown in Fig.

When preferred, bearing-blocks the direction indicated by the arrow on Fig. 3 to force the plungerG inwardly. At the beginning of this inward movement theplunger G will be moved quite rapidly, by reason of the long end of the workingbeams (3 bringing about that result. As the plunger G progresses in its inward movement, the pitman E will be swung sidewise into contact with the friction-roller H at the side of the press toward which said pitman is swinging, and the effect of this contact will be to force the working-beams O to slide endwisc, so as to bring their pivot c nearer the shaft B, and thereby the leverage of the opposite end of said working-beams (that is to say, the end connected to the sweep D) will be correspondingly increased. Then as the movement of the sweep is continued in the direction indicated, and the resistance of the material being compressed increases, the working-beams C will continue to move end wise until the end of the slots 0 nearest the pivot c is brought against the shaft 13, and the maximum of the increase of leverage will be attained, and the same will be maintained until the center lines of the working-beams O and pitman E are brought to range in line with each other, as shown in Fig. 1; but by the continued movement of the sweep D, as soon as the pitman is carried slightly past the center linejnst described, the resilient action of the compressed material will cause the plunger G to rebound, thereby forcing the workingbeams G to the other extremity of their movement at the side of the press from which it last started, and in effecting this movement the slotsfof the links F permit said links to slide on the studs d and the working-beams C will slide on the shaft B until the opposite end of the slots 0 (that is to say, the end of said slots nearest to the link F) will bear against the shaft 13, as shown in Fig. 3, when the parts will be in position for a repetition of the operation above described.

\Vhen preferred, one of the working-beams C and links F may be dispensed with, and the press will be operative, and my invention includes such a modification; but as the strains are better equalized in the construction hereinabove described, I prefer to retain those parts.

I claim as my invention 1. In a baling-press, the combination, with astationary shaft and a sweep pivoted thereon, of working-beams provided with a longitudinal slot, whereby said working-beams are adapted to both oscillate and slide endwise on said shaft, slotted links which connect one end of said working-beams to said sweep, and a pitman which connects the opposite end of said working-beams to the plunger of the press, as and for the purpose herein specified.

2. In a baling'press, the combination, with a plungerpitman, astationary shaft and workingbcams provided with a longitudinal slot, whereby said workingbeams are adapted to both oscillate and slide endwise on said shaft, of frictioirwheels lined in the path of said pitman, whereby the initial sliding movement is imparted to said working-beams, as herein specified.
